The manual is
on the Fluke web site and includes calibration
procedures.
Would it be too much to ask for you (or someone) to point me at it
directly? [...website trouble...]
http://assets.fluke.com/manuals/87______umeng0800.pdf
is the "user's manual". There are other manuals listed for variants
of the 87.
That one just refers to the service manual for calibration, and
assets.fluke.com/manuals/ doesn't let me list its contents - I don't
suppose you have a pointer to the service manual? (This one is
certainly very useful; for example, it taught me about modes like
capacitance and duty cycle. But it punts on calibration.) I tried
guessing a few names, like 87______smeng0800.pdf or 87______sm0800.pdf
or 80______sm.pdf, and all I got were 404s.
